Ok I am having problems with my right nipple only. Its sore to the touch its seems to leak something yellowish and its crusty. I am NOT pregnant, not breastfeeding, just a woman with this problem. I've tried looking up answering on this but every article is about breastfeeding. And then I found a few about the sore nipples being somekind of breast cancer. Im due for my GYN appointment but I want to know what I can do for the pain while waiting to be seen.
